To a'zzy Beit lmown-'that we,-' iJoHN B. WINFIELD and Cii'anins1 F.- ACKERMA, citizens of thc county of Richland and State of Ohio, have Vinvented certain newffand useful Improve# mentsSpraying-Nozzles; and we do dcclare thefollowing to be a full, clear, and exact description of the invention, such as Will enable others skilled inthe art to which it ap that shown in Figs.` l and 2.

pertains to make and use the same.`

invention relatesto new and useful improvements in spraying nozzles.

AThe principal object of the invention is to provide a spraying nozzle embodying means for quickly vcleaning the spraying tip and f of disassembling any x Without the necessity of the parts.

Withthese and other objects in view, the

invention consists vof certain novel features `I 'of construction, combination and arrangement of parts, as Will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a central longitudinal section of a nozzle constructed in accordance with the invention, the spraying tip 1n sprayingposition;

Fig. 2 is a similar view, the spraying tip' in cut-ofi positlon; and, F 1g. 3 1s a slmilar view illustrating a slightly modified form of the invention.

the embodiment illustrated, the nozzle "comprises a tubular casing 1 provided with an interior thread 2 at one end whereby it may be screwed to a suitable hose connection .y

and with an exterior thread 3 near its opposite end, u on which is adapted to screw a bonnet 4, tlie outer end of which is closed by an end Wall 5 having a central tip receiving opening or aperture 6. The exterior threadg ed end of the casing 1 is closed in by a Wall 7 provided With a central longitudinal coneshaped disgorging or cleaning pin 8 adapted to extend through a corresponding central aperture 9 produced in the outer end Wall 10 of a spray tip 11 mounted to slide longitudig nally within the bonnet, the inner end ot' said tip having an annular rim 12 which ts against the inner surface of the bonnet, and

which limits the outward movement of the tip by engaging the end Wall of the bonnet.

The outer end of the casing 1 is provided beyond its exterior thread 3 with a spiral groove 13, the inner end of which comniunicates With the interior of the casmg 1 by a specification ofn'temratenr." i Apncauon med August 2o, 190s. serial Na. Masas.

l port 14 formed in the wallof said casing.

Patented i l The body of the casing 1 is provided with a plug 15 of any ordina l by 'the supply i cut oit. i In the modified form ofthe invention illustrated in Fig. 3 of the drawings, .the plug 15 is dispensed with but in all other repec-ts the g construction of the nozzle is identical with of liqui may be permanently In practice; the liquid asses from the construction, where-4 4leasing 1 through the out et port 14' and f around the spirals of the spiral groove 13 in the outer surface and outer end of the casing, the spiral groove imparting a whirling or rotary movement to the liquid and causing it to pass through the spray 'tip in a circular spray.

lt Will therefore be noted that by employing the construction to which We resort the most delicate plants or vines may be sprayed Without danger of damaging the same in any g respect.

It will be further noted that to clean the l spraying tip, it is only necessary to press the latter againsta limb or t-he like to cause g the disgorging pin to enter the aperture 9 i thereof, after which operation the spraying tip Will be immediately returned to its for- -mer position by the ivater pressure. i The plug 15 is used when it is desired to out ofi the supply of liquid for an appreciable l period of time, as in moving from one tree to another.

,i From the foregoing description, taken in connection With the accompanying drawings, the construction and operation of the y invention Will be readily understood Without requiring a more extended epla'nation.

Y Various changes in the form, proportion and the minor details of construction 'may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention as deiined in the appended claims.

Having thus described our invention, what We claim as new and desire to secure by Letters-Patent is 1. A spraying nozzle comprising a tubular casing closed at one end and provided near said end with an outlet port, a bonnet screwging over the closed end of the casing. a y spraying tip having a central aperture, mounted to slide in the bonnet in front of the closed end of the casing and a disgor'ging pin projecting from the closed end of .-the

,casing and adaptedto enter the aperture of the spraying' tip when the latter is moved inward into inoperative position.

AA spraying nozzle comprlsing a tubular casing closed at one end and having an exte-Y rior spiralgroove at its closed end and an outlet port leading from the interior ofthe casingto the inner end of said groove, a bonnet screwing over the closed end' of the casing and prof' ecting in advance of the same', a cylindrica spraying tip mounted to slide longitudinally in the-projecting end of. thebonnet, and having a centralaperture to permit lthe passage of the spraying fluid therethrough when; in operative position` and a longitudinal disgorging pin projecting from the closed endl of the'casing adapted to enter ter is moved inwardl)T into inoperative position. j

3. A spraying nozzle comprlsmg a tubular casingclosed at one end, havinga spiral eX- terior groove'at said end and an outlet port leading from its interior tothe inner end ,of

: said groove, a bonnet screwing over the closed end of the casing and projecting inadvanceof the same, a portion of the innersur-v face of said bonnet fitting snugl)T against the grooved portion 'of the easing, a cylindrical apertured spraying tip mounted to slide in and through the projecting end of the bonnetf and a longitudinal disg'orging pin-'profjecting from theclosed endof the casingand said groove,.a bonnet screwing over the closed Iend of the casing and projecting in advance of the same, a' portion of the inner surface of -said bonnet iitting snugly against the grooved portion of the casing, a cylindriealapertured spraying tip mounted toslide in and through the projecting endof the bonnet andalou i-l tudinal disgorging pin pro]ecting from t e closed end of the casing and ada ted i'lo'enterY` the aperture. of the sprayingtip hen the latter is vmoved inwardlyT into inoperative ppsi-A tion and a cut oiiplug arranged 4.near the.
